Nice little kit these, I built one a little while ago (part way down page 13 of my project thread) mine has a 17.5 brushless fitted, bombs along well

@alvinlwh I don’t actually remember, think it was a pretty straight forward build. Is the BL motor you’ve got a sensored motor? I believe the Tamiya ESC’s will only work with a sensored motor

Yes, sensored. With all the flashing lights looking the same to me, I may not have set it correctly though. Anyways BL is getting expensive and troublesome for not a lot of gain, I will probably stick with brushed in the future. 

Yeah that certainly wouldn’t help, they definitely can be fiddly ESC’s too, where you do the same thing and it works after not working. BL is definitely far more maintenance friendly in the long run, but the old brushed motors still hold a lot of nostalgia for me

Fun cars, they are.  The plastics are a bit brittle; I suggest purchasing parts SAK-M4P17 and SAK-M4P18.  If it will be driven outdoors on asphalt, it would also benefit you to look for the softest damper springs you can find to increase traction.

Spool the front, diff the rear.  And be very gentle with the tiny bolts that hold the bearing carriers, hey are easy to strip.

Opps, thanks for the correction. Editing now. 

Will probably need a new carrier, I think I stripped one, or maybe superglue can fix it. Or do you know if SAK-U420 (or the other number of teeth ones) will work? 

I believe SAK-U421/V3 is the direct aluminum replacement for the center pulleys, as they are the parts used on the M4 Pro model.  I couldn't say if the change to alloy over plastic is worth the increase of rotating weight.

Regarding the stripped carrier, you may be able to  add a thin coat of epoxy to add material back to the hole.  There's no load on the screw, so it's not too critical that it snugs up tight; it just has to prevent the carrier from rotating.  That's one component I was waiting for in alloy.  About a year ago they had their parts page with a "coming soon" description for aluminum carriers for one of the Sakura cars that would also fit our M4's. 

I just noticed that 3racing updated their website.  Cross-referencing parts will be more challenging now.  From what I had found, they have roughly 3-4 designs used in the touring cars, with different combinations of those designs used in various models.  If you need other part interchangeability info, I can reference my ebay purchases for P/N's.
